8.3.2 Cleaning the Mirrors
After you have removed each mirror, you will want to inspect each mirror for scratches, smoke residue, or debris.
If any residue or debris is present, use the following steps to clean the mirrors.
1) Hold the mirror with the reflective side up, without touching the reflective side of the mirror (DO NOT apply
any finger pressure or any other cleaning solutions to the mirror surface).
2) Drape a new sheet of lens tissue over the mirror.
3) Apply a few drops of methanol on the tissue covered mirror (apply enough so that the tissue absorbs just
enough solution to cover the mirror surface).
4) Pull the tissue across the mirror in only one direction.
5) Repeat the cleaning processes if the mirror is not completely clean after the first attempt.
6) Make sure that the mirror is completely dry before reinstalling it.
